Work sequence  

    

During test and assembly work 
Diagnostic Trouble Codes (DTCs) 
can be detected from other control 
modules like e.g. connector 
disconnected. Therefore on 
completion the DTC memories of all 
control modules must be checked 
and erased. To do this:  

When a control module answers with 
its identification the number of stored 
Diagnostic Trouble Codes (DTCs) 
appears on the display or "No fault 
detected".  

Any system Diagnostic Trouble 
Codes (DTCs) that are stored will be 
displayed one after the other and 
printed out. The VAG 1551 will then 
transmit the next address word.  

-  Connect VAG 1551 scan tool (or 

VAG 1552) using VAG 1551/3 
adapter cable. 

-  Press button -0- twice for address 

word "Automatic test sequence" 
and confirm entry with -Q- button. 
VAG 1551 transmits all known 
address words one after another.
